Abstract

The utility model relates to a dustproof mask. The main body of the dustproof mask is formed by splicing the left and the right two olive shapes, wherein, the middle of the main body is provided with a piecing seam, the circumference is provided with seam strip edges, the inner surface at the top is provided with a nose cover, and the right and the left two sides or the upper and the lower parts are provided with flexes. The main body is formed by five layers of materials, such as a terylene at an outer layer, a foam cotton activated carbon at an inner layer, T99 filter cloth, terylene, etc. The utility model has the advantages of good effect of dust filtration and dust prevention, soft and elastic materials, long service life and strong applicability.

Description

Dustproof mouthpiece

The utility model relates to a kind of anti-dust respirator, belongs to the technical field of breathing apparatus.

In the dust workplace, in order to prevent or mouth mask is generally used in the invasion and attack of dust, mostly utilize cotton gauze to make rectangularity, in two-layer cotton, add cotton, there is the connection rope band both sides, be used for lying in two ears, its shortcoming is that mouth mask presses mouth nose position, and the time just has the sensation of feeling suffocated slightly for a long time, some anti-dust respirator also has the aerated plastics of use to make, its moulding is coarse and crude, and the part of similar simply breathing mask is out of favour in the use.

The purpose of this utility model will provide a kind of anti-dust respirator, and it can restrain the above-mentioned deficiency of clothes, and its beautiful design selects for use light and soft material to combine, and dustproof effect is better, can resist the propagation of bacterium.

The main body that the purpose of this utility model is achieved in that anti-dust respirator by about or two olive shape up and down, the sheet stock splicing of ellipse garden shape is formed, the left and right sides has elastic cord top to be sewed with the nose cup of ellipse garden shape sheet stock, and mask main body is by two layer materials, skin is a terylene, and internal layer is that the foam nexine is the T99 filter cloth, also can add layer of active carbon and terylene layer in case of necessity, material is flexible, flexibility, not fragile, gas permeability, strainability is all good, uses not have the sensation of feeling suffocated.

The front view of Fig. 1, mouth mask.

The side view of Fig. 2, mouth mask.

The schematic diagram of Fig. 3, mask main body.

Fig. 4, mouth mask operating position schematic diagram.

Now in conjunction with the accompanying drawings the structure of mouth mask is described in detail:

By Fig. 1, mask main body (1) be by about 2 olive shape or ellipse garden shape be put together, there is a splicing seams (2) centre, there is a seam bar limit (3) to sew up a nose cup (4) again all around in top inner surface, it also is similar to an ellipse garden shape thin slice, then up and down position or position, the left and right sides sew up rubber-like elastic cord (5) splicing seams (2) can vertical cube to, also can be the direction of level.

Fig. 2, be the side view of accompanying drawing 1.

The main body of mouth mask (1) is formed by three layers, and outer (6) are terylenes, and is both soft; good air permeability, durable in use, can play a protective role to mouth mask; not fragile, internal layer (7) is a foam, and main feature is that dustproof effect is good; is rich in resilient flexible; be used for rubbing with the hands and touch, be rich in soft sense, the 3rd layer of nexine (8) is 2 grades of passing materials of the military survey of T99 filter cloth; sew on seam bar limit (a 3) nose cup (4), and 2 elastic cords (5).

Fig. 3, be the schematic diagram of mask main body.

Mask main body (1) can combine by five layers, outer (6) are terylenes, and second layer internal layer (7) is still foam, and the 4th layer of nexine (8) also is 2 grades of passing materials of the military survey of T99, but the 3rd layer (9) increasing are active carbons, and layer 5 (10) is a terylene.

Some industry such as textile mills can simplify, and are terylenes as long as adopt skin, and that internal layer is a foam is just passable.

The schematic diagram of Fig. 4 mouth mask operating position

During use, anti-dust respirator is placed on the mouth and nose position, and elastic cord (5) can be enclosed within two ears or head and neck location.

Because its space of its shape (11) of mouth mask is bigger, will never produce the sensation of feeling suffocated when therefore using, nose cup (4) can cover bridge of the nose part, aqueous vapor when breathing can not risen, influence the definition of glasses, the flexible softness of terylene material, characteristics through grinding, access times increase, the filtration of foam and T99 filter cloth is better, to dustproof effect, its effect is particularly remarkable, if add active carbon layer, effect is better, is particularly useful for the department of dust work.

Claims
